- Around line 1495-1497: The dynamic selector validation in _parse_input_spec
must inspect raw COMFY_DYNAMICCOMBO_V3 option dictionaries before keyless
entries are filtered out, so options with inputs but no key raise the existing
ValueError instead of disappearing. Preserve duplicate and non-string key
checks, and add coverage for the missing-key case in the selector-key test.

🟠 High — widget_layout expands branches when port.is_dynamic_combo or port.dynamic_options, but _expand_widget_entries (backing widget_order/widget_order_default) requires port.dynamic_options and _is_dynamic_combo_type(port.type). A selector declared under a plain "COMBO" type with dict-form {key, inputs} options — the shape _parse_input_spec detects structurally — has dynamic_options set but is not a COMFY_ type, so widget_layout emits branch sub-slots that widget_order publishes as one flat slot: the two projections pinned by the same catalog_version disagree about how many slots the class consumes, which is the silent wrong-index divergence this catalog exists to prevent. Use the same predicate in both. Raised by 4 of 6 reviewers (claude-opus-5-thinking-max adversarial, kimi-k3-high adversarial, claude-opus-5-thinking-max edge-case, kimi-k3-high edge-case).

Confirmed for widget_order_default and widget_order_for_node. Four new regression cases fail locally; hosted confirmation precedes the fix.
Full context for agent readers
Graph.widget_order intentionally exposes only the selector, independently of selected values. It does not use _expand_widget_entries; changing that API to expand fields would alter its contract. The catalog's widget_order field instead uses Graph.widget_order_default. That default walk and the value-aware walk both incorrectly require the V3 type name despite the parser retaining plain COMBO branch declarations.
The tests exercise default and non-default choices with different child counts, both at top level and nested under a typed selector, followed by a seed and its companion slot. Expected names are independent of implementation output. All four cases fail on missing branch fields; the existing 34 catalog tests pass. The value-independent API is separately asserted unchanged. Scoped Ruff and mandatory hooks pass. No production fix is in this test commit and this thread remains open.
Glossary: structural combo means a plain COMBO selector whose option objects declare child fields; companion slot means the serialized seed-control value following its seed.

Fixed the order divergence in the separate implementation commit. All 351 targeted tests pass; fresh hosted checks are pending.
Full context for agent readers
Hosted pytest on the test commit confirmed exactly four expected failures, 7873 passed and 38 skipped. The one-line change makes _expand_widget_entries recognize structurally parsed dynamic_options, matching widget_layout. It preserves the value-independent Graph.widget_order API and changes no test assertions. Full Ruff lint/format and mandatory hooks pass.
This addresses default and selected-mode field ordering, including nesting and following fields. It is not a claim that structural selector switching rematerializes children correctly: _write_widget still gates selector rematerialization on the type name. That existing separate behavior needs a bounded follow-up before claiming full structural-combo editing support. Other producer review findings and consumer integration remain open.
Glossary: rematerialization means rebuilding child values when the selected option changes.

Ordering and sequential selector writes now pass hosted tests. The separate switch fix closes the gap noted in my earlier reply.
Full context for agent readers
Ordering verification passed after four confirmed failures. Switch verification passed after three confirmed failures. The unchanged tests cover typed/structural parent and nested selectors, growing/shrinking children, edits, same-choice preservation, replay and unequal surrounding values. Sequential operations advance base_version so these assertions measure ordered edits rather than random tie-breaks.
Current full pytest passes: 7898 passed, 38 skipped. This proves CLI behavior, not multiplayer convergence or live template acceptance. The separate GPU dependency job remains red; the PR is not merge-ready.
Glossary: selector means a choice controlling child fields; convergence means replicas reach the same result despite different operation arrival orders.

🟠 High — Both new guards raise ValueError, and build_types calls widget_layout for every class with no per-class isolation, so a single third-party node with a duplicate key, a non-string key (_parse_input_spec keeps any option dict that merely has a key), or nesting past _MAX_DYNAMIC_COMBO_DEPTH (line 1492) aborts comfy nodes widget-catalog for every other class. Every sibling walk over the same data degrades instead (_expand_widget_entries just returns at the depth cap) and widget_order_default handles these classes fine today; since object_info can come from a remote server or --input, prefer skipping or marking the offending class, or emit a structured warning like the existing object_info_stale path.

Deliberate tradeoff, now documented: reject the whole catalog rather than silently drop known classes.
Full context for agent readers
build_types promises every known class, distinguishing unknown classes from known widget-less classes. Skipping an invalid class would erase that distinction; a warning-only partial result would require a new consumer contract. The proposed catalog therefore rejects unsupported keys, unavailable choices and excessive nesting with class/field context. General graph parsing remains permissive. This can prevent catalog generation because of one third-party class; that availability cost is intentional and remains visible for human review, not claimed away as a harmless error.

🟡 Medium — Excluding injected upload/audioUI slots makes widget_layout unable to consume workflows saved by older frontends, which wrote real trailing values into them — the rationale this PR deletes from widget_catalog.py said exactly that, and widget_order still names them so a workflow saved by either frontend decomposes. Because the new schema directs consumers to "Require exact consumption, not padding from defaults", a LoadImage/LoadAudio workflow with those legacy trailing values now has more values than slots and a conforming consumer must reject it; represent them as optional legacy slots or state an explicit compatibility rule. The hardcoded name set is also fragile: any name later added to frontend_extra_widget_names silently becomes a serialized slot and shifts every later index. Raised by 3 of 6 reviewers (claude-opus-5-thinking-max adversarial, gpt-5.6-sol-max adversarial, claude-opus-5-thinking-max edge-case).

Documented the current-frontend boundary. Historical upload/audio values are unsupported, not silently discarded.
Full context for agent readers
The prototype targets current serialization: injected upload and audioUI consume no values; PREVIEW_3D image does. Older arrays with extra upload/audio tails must fail exact consumption. There is no optional legacy slot or compatibility repair in this change. The schema and producer documentation now say this explicitly. Your separate concern about future injected names remains open; this documentation change does not make the hardcoded filter future-proof.
There was a problem hiding this comment.
The current helper emits only upload, audioUI and image; all three have explicit handling. Future-name handling remains an extension obligation, not a compatibility feature in this prototype.
Full context for agent readers
I checked frontend_extra_widget_names: current upload/audio controls are excluded and the injected 3D image is retained. The historical-array limitation is already documented: extra trailing values must fail exact consumption, not be silently dropped. There is no current unhandled injected name demonstrated by this finding.
I am not adding a speculative metadata abstraction for future helper additions. Any new injected control must define and test whether it serializes and whether it permits writes at that source change. This is a scope disposition, not a claim that the current hardcoded filter is future-proof or that a reviewer has accepted the tradeoff.

🟡 Medium — A dynamic combo whose options block is absent or unparseable yields dynamic_options == [] — a shape _is_link explicitly supports ("a dynamic combo is a widget port even when its options block is missing or malformed", e.g. remote combos whose choices the frontend fetches at runtime) — and this emits "options": [], indistinguishable from a selector that genuinely declares zero branches. Combined with the schema's "Consumers must reject unknown selections", every stored value of such a selector becomes undecodable; omit the options key entirely (or mark branches as unknown) rather than emitting an empty list. Raised by 3 of 6 reviewers (claude-opus-5-thinking-max adversarial, claude-opus-5-thinking-max edge-case, kimi-k3-high edge-case).

Confirmed; tests-only reproduction is pushed. Hosted failure confirmation precedes the fix.
Full context for agent readers
Missing metadata, an absent options key, null and non-list declarations all currently collapse into options: []. The new top-level and nested cases fail at the expected missing exception: 8 failed, 40 passed locally. Explicitly empty lists remain valid and are asserted independently, including their structural identities. Normal hooks and scoped Ruff pass. Hosted pytest is pending.
The proposed boundary fix rejects typed dynamic selectors without an explicit options list, naming the class and complete field path. Omitting options would make the selector look like a safe single-slot field even though its children are unknown. No new unknown-layout wire variant or remote lookup is proposed. This deliberately refuses the whole catalog, consistently with unsupported selector keys, rather than publish partial metadata. General graph parsing stays permissive; an explicit empty list remains distinct from unavailable choices. No implementation change has been made yet.

Fix pushed after hosted reproduction. All 361 targeted tests pass; full hosted verification is pending.
Full context for agent readers
The tests-only hosted run confirmed exactly eight missing-rejection failures, 7879 passed and 38 skipped. The separate fix uses the existing Port.enum_declared distinction inside Graph.widget_layout, before link filtering. It refuses typed dynamic selectors without an explicit list, with the class and full field path in the error. Explicitly empty lists remain valid; no regression assertions or general parser behavior changed.
The schema now documents that this refuses catalog generation rather than omitting unknown children or inventing an unknown-layout wire variant. Local catalog, engine, frontend-slot, dynamic-edit/list, dictionary-widget and seed-companion tests all pass in 1.10 seconds. Full Ruff lint/format and mandatory hooks pass; the normal push was read back remotely. No full-suite success is claimed for the new commit yet. Other review findings and consumer integration remain open.

Hosted verification passed for the unavailable-choice fix. Missing metadata now refuses generation; explicitly empty choices remain distinct.
Full context for agent readers
This supersedes the pending-verification statement above. The tests-only run confirmed eight failures before the separate fix; the fix passed 7889 tests with 38 skipped. Current full pytest passes 7898 with 38 skipped.
The class and complete field path identify the invalid declaration. General graph parsing stays permissive. This intentionally rejects the whole catalog rather than publish a single-slot field whose children are unknown; no partial-catalog or remote-choice discovery contract is introduced. The separate GPU job is still failing.

🟡 Medium — This walk recurses into every key at every level, so emitted entries grow as O(keys^depth), whereas _expand_widget_entries descended into only the selected key per level and _MAX_DYNAMIC_COMBO_DEPTH was sized for that linear walk — ~10 nested selectors of 4 keys each explodes long before depth 16, and nothing caps the resulting per-class or total payload. _dynamic_combo_sub_ports also linear-scans dynamic_options once per key, making expansion quadratic in the option count; resolve keys to options once into a map and bound emitted entries, not just nesting depth.

Fixed the repeated sibling scan, with hosted red-to-green evidence. This does not establish a total payload or memory bound.
Full context for agent readers
The tests-only run confirmed two failures. At widths 16 and 64, the old implementation read option keys 152 and 2144 times; exact complete layouts already matched. Passing the already-known option as a singleton to _dynamic_combo_sub_ports removes the repeated scan without another map or parser. The unchanged linear-work assertions pass in full hosted pytest: 7895 passed, 38 skipped.
The input already stores the complete branch tree. This walk does not generate a Cartesian product of independently declared options, so growth measured against nesting depth alone is not additional algorithmic expansion. Emitted identities do carry ancestor paths, adding depth-dependent output overhead. The depth-16 guard is not a total payload cap, and counting dictionary lookups does not prove a memory or total-CPU bound. No arbitrary cap is added in this prototype. A total-size admission policy remains a separately reviewable limit, not something these tests establish.
Glossary: branch tree means the nested options already present in object_info; identity means the serialized field path qualified by ancestor choices.

🟢 Low — The uniqueness/type check runs on port.dynamic_options, which _parse_input_spec has already filtered: option entries that are not objects or that lack a key were silently dropped earlier, so those branches vanish from the advertised all-branch layout (and do not move catalog_version) instead of being rejected. If the contract is that unsupported input is "rejected during generation, never coerced", validate the raw options list before filtering. Raised by 1 of 6 reviewers (gpt-5.6-sol-max adversarial).

Fixed at the raw-declaration boundary. Malformed entries now fail before filtering can hide them.
Full context for agent readers
Tests-only hosted pytest confirmed eight failures for missing keys and non-object options, across typed/structural selectors at top-level and nested positions. The separate fix passed: 7873 passed, 38 skipped, with assertions unchanged. Current full pytest also passes. This is the same root cause as the CodeRabbit finding already confirmed addressed, not a second parser change.

🟢 Low — The injected PREVIEW_3D image control is given a plain [["field", "image"]] identity, making a frontend-injected slot with no declared schema port indistinguishable from a real field, while the equally synthetic LOAD_3D buttons a few lines above are tagged companion. A consumer holding only widget_layout will treat the viewport slot as a writable edit target even though frontend_injected_widget_names exists precisely because it never is one. Raised by 1 of 6 reviewers (claude-opus-5-thinking-max adversarial).

Clarified serialization versus write permission. Keeping the consumer-enforcement concern open.
Full context for agent readers
widget_layout describes serialized positions, not editable targets. The schema now explicitly states that an identity does not authorize writing, including the injected PREVIEW_3D image. Existing CLI writes use schema-backed entries through _editable_widget_names, but a new consumer holding only this layout cannot reconstruct that permission boundary. Documentation alone does not solve that integration gap: the consumer contract still needs an explicit, tested way to preserve injected values while refusing edits. No identity or permission behavior changed here.
There was a problem hiding this comment.
Added explicit read-only metadata; hosted tests pass. Consumer write refusal is still required before adoption.
Full context for agent readers
Tests-only hosted pytest confirmed two missing-metadata failures. The separate fix marks injected PREVIEW_3D image and LOAD_3D buttons read_only: true, preserving identities and positional order. A declared image field with the same name/identity remains writable, and writable seed companions stay unchanged. Tests also assert literal button ownership/order and JSON Schema validity. Full hosted pytest passes: 7898 passed, 38 skipped.
Correction to my earlier description: _editable_widget_names is not a complete permission allowlist because it omits writable seed companions. Existing CLI writes distinguish injected entries separately. New consumers must preserve injected values on import/projection and refuse their edits before mutating the document. Absence of read_only does not bypass active-branch, ambiguity, selector-switch or other checks. Metadata emission is fixed; consumer enforcement is not implemented here. The GPU dependency job remains red.

⚪ Nit — The description asserts "Keys must be unique strings within this selector", but nothing in the schema enforces it, so a catalog carrying duplicate keys validates clean even though the producer aborts on it. JSON Schema cannot express uniqueness over a child property directly, so either document the required consumer-side key check or note that validation alone does not guarantee unambiguous identities. Raised by 1 of 6 reviewers (claude-opus-5-thinking-max adversarial).

Documented the required consumer check: validate unique keys within each selector explicitly. JSON Schema validation alone is insufficient. Producer rejection remains unchanged; consumer enforcement belongs to the integration tests.

⚪ Nit — LOAD_3D button slots are appended before the field whose identity they claim companionship to, whereas seed companions are emitted after their owner and the schema describes companions as owned by their preceding field. The positional order is correct for serialization, but a consumer resolving ownership by the documented preceding-field rule will attribute the buttons to the wrong widget. Raised by 1 of 6 reviewers (kimi-k3-high edge-case).

Corrected the ownership rule: remove the final companion component from the identity to find its owner. Never infer ownership from adjacency. LOAD_3D buttons precede their owner; seed companions follow it. Serialization order is unchanged.

Changes
widget_layoutdescribes serialized fields recursively, including branch-qualified structural identities and owner-qualified seed companions. Injected upload/audio controls consume no serialized value; PREVIEW_3D image and LOAD_3D buttons remain included. Dynamic selector keys must be unique strings. The existing canonical catalog hash now covers every branch. Default and value-aware flat orders and CLI selector-write/default rebuilding now recognize structurally declared dynamic combos; value-independentGraph.widget_orderis unchanged.The schema documents the proposed format. This does not make existing document consumers selector-aware or fix any particular template-loading session by itself. Consumer import/edit integration and multiplayer selector switching remain separate changes. No cloud database harness, migration, release, or deployment is included.
Review Focus
Review the recursive wire format, serialized participation, branch identity and preserved array order. The real Magnific fixture comes from pinned ComfyUI source, captured September 22. Tests cover every mode, a following field, nested repeated names, independent seed companions, media/3D slots and invalid selector keys. The implementation commit changes no test expectations.
